Crystal Jensen is my cousin, and she has done so much, Peterson side, I have a lot of the Farm is in Ne.I am working with a cousin there. The Volk side is from John Volk, from Pa. The Burge side is from Lake County, Indiana. The Richardson side is from Gary, In, and Involves the Ran's side of the family also.
